Screen zoomed in

So my minecraft is zoomed on the top left corner and i have tried EVERYTHING from looking into my settings to re installing minecraft and using the repair feature. This has been bugging me for the past 3 days and have searched on youtube and asked people on planet minecraft and no one has anything on how to fix this. I asked mojang support on twitter and they told me to come here. The only way its not zoomed in is when i have it out of fullscreen.
